Hybrid tea rose plant named &#39;ruiy5991&#39;

ABSTRACT

A new and distinct Hybrid Tea Rose plant having attractive red and white bicolor flowers.

BACKGROUND OF THE INVENTION

[0001] The present invention relates to a new and distinct variety of rose plant of the Hybrid Tea rose class, which was created by crossing as seed parent an unnamed, undistributed seedling and as a pollen parent the variety known as ‘RUIZON’. The varietal denomination of this new rose is named ‘RUIY5991’.

SUMMARY OF THE INVENTION

[0002] Among the novel characteristics possessed by this new variety which distinguishes it from its parents and all other varieties of which I am aware are its attractive red and white bicolor flowers.

[0003] Asexual reproduction by propagation by grafting of the new variety as performed in De Kwakel, The Netherlands shows that the foregoing and other distinguishing characteristics come true to form and are established and transmitted through succeeding propagation.

COMPARISON WITH PARENTS

[0004] Among other respects, the new variety differs from its parents in flower color, inasmuch as the seed parent has flowers that are red inside and white outside; and the pollen parent has red flowers, whereas the new variety has flowers that are red inside and white outside with the red color being brighter than the seed parent.

BRIEF DESCRIPTION OF ILLUSTRATION

[0005] The accompanying illustration shows a typical specimen of the new variety depicted in color as nearly true as is reasonably possible to make the same in a color illustration of this character. In the illustration are shown: new growth 1; leaflets 2, 3 and 4; stem with thorns 5; flowers in different stages of development 6, 7, 8 and 9; and reproductive organs 10, 11 and 12.

DESCRIPTION OF THE NEW VARIETY

[0006] The following is a detailed description of the new variety with color terminology in accordance with The Royal Horticultural Society Colour Chart (RHSCC). The terminology used in color description herein refers to plate numbers in the aforementioned color chart. Phenotypic expression may vary with light availability, environmental and cultural conditions.

[0007] The following observations are made of 9-month old plants grown in a greenhouse in De Kwakel, The Netherlands during January from a grafted cutting.
